The Barr Tribunal was a Public Inquiry in Ireland established by Resolutions passed by the Dáil Éireann and the Seanad Éireann on 17 and 18 April 2002, and by Instrument entitled Tribunals of Inquiry Evidence Acts 1921 (Establishment of Tribunal) Instrument (No. 2) 2002 made by the Minister for Justice, Equality and Law Reform on 1 July 2002.
The sole member of the Tribunal was Justice Robert Barr. The Tribunal was charged with investigating the facts and circumstances surrounding the fatal shooting of John Carthy (by members of the Garda Síochána) at Abbeylara, County Longford on 20 April 2000.
John Carthy, a then 27-year-old native of Toneymore, Abbeylara, Co Longford, on 19 April 2000, went to the cabinet within which was his shotgun.
He brought it, a full box of cartridges and his gun belt back to the kitchen remonstrating, according to his mother, that "no one was going to put him out of his house". He loaded the gun with two cartridges, went outside the hall door and discharged two shots. It is not quite clear whether John then forced his mother out of the family home, or whether she left at her own volition. However, Rose Carthy left the family home and went to her sister's home, two doors away. Mrs Carthy informed the Barr Tribunal that her son did not order her out of the home, despite rumours to the contrary at the time and news reports. She was, however, very afraid for her son.
Rose Carthy asked her sister, Nancy Walsh, to ring the Gardaí in Granard, three kilometres away, to come out and "take the gun from John". Two Gardaí, John Gibbons and Colin White, were dispatched to the scene. Garda Gibbons war armed. At approximately 17:55 on Wednesday 19 April 2000 the two Gardaí drove into the driveway of the Carthy home. Two shots were fired in rapid succession from an unknown place and in an unknown direction. They quickly reversed their car and observed the Carthy home from a safer distance. At this stage John Carthy's general practitioner, Dr. Patrick Cullen, was called to the scene. While waiting for Gardaí he said that approximately ten shots were fired "out the back of the house". Detective Garda Campbell attempted to talk with John Carthy but, in his evidence, said Carthy replied with an expletive and a threat to blow his head off.
